Subtask Behavior Improvements

What is the status of subtask improvements? For example, allowing parent tasks to have their due date determined by the next subtask that is due. This would solve the dilemma of having to either (1) keep all subtasks expanded all the time so that none get overlooked, or (2) hiding subtasks to reduce clutter and taking the risk that they will be forgotten.

I found the following quote in another thread, and wondered whether any progress has been made. I created a new thread because the thread I quoted (http://www.toodledo.com/forums/2/3308/-35961/subtasks-with-the-iphone-app.html) was about more things than just subtasks.

We plan to allow subtasks and parents to inherit information from each other in a future update.
